TPS71728DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input to the device; 0.1-μF to 1-μF capacitor is recommended for better performance. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable pin; driving above VEN(high) turns on the regulator, driving below VEN(low) puts regulator into standby mode and disables output. |
| 4 | NR | passive | Noise reduction pin for fixed voltage versions only; connects to a capacitor that filters noise from internal band gap to lower output noise. |
| 5 | OUT | power_out | Regulated output voltage; minimum 1-μF capacitance to ground is required for stability. |
